Neon Reefer Posted May 17, 2013 Share Posted May 17, 2013 Does anyone know anything about these new LED flood lamps that are out w/ the Epistar Modules? I was considering putting 2ea on a 75 gal 48 x 18 x 20 and wanting to grow SPS Total price tag $300 Here are the stats. What do you think? I beleive the total package is around 12500 - 13000 Lumens output For 50W lamps:- Input voltage: AC 85-265V 50-60Hz- Power consumption : 50W-Color Temperature: 14000K- LED quantity: 1pcs- LED sources: 1pcs Epi-star 50W Module LEDs- Material: Aluminium extruded sections- Beam Angle: 120 degree- Lights Size: 11in * 9in * 2.5 in- 4.85 lbs- Certificated: CE and ROHS- Warranty: 2 years- 110V Plug- 50,000 Hour LifeSpan (17 YEARS at 8 hours a day) For 20W Lamps: - Input voltage: AC 85-265V 50-60Hz- Power consumption : 20W-Color: 455 nm Actinic Blue- LED quantity: 1pcs- LED sources: 1pcs Epi-star 20W Module LEDs- Material: Aluminium extruded sections- Beam Angle: 120 degree- Lights Size: 7in * 5.5in * 4.3in- 1.65 lbs- Certificated: CE and ROHS- Warranty: 2 years- 110V Plug- 50,000 Hour LifeSpan (17 YEARS at 8 hours a day) Quote Link to comment Share on other sites More sharing options...
10gReef Posted May 17, 2013 Share Posted May 17, 2013 I have a daylight on on my sump over some Cheato and it does great. not sure your going to get the best spectrum for coral growth thought. I have an 48" coralife powercompact I would sell. I have seen folks keep sps under similar lighting on smaller tanks. as long as you can place the corals high in the tank I bet it would work. 1 Quote Link to comment Share on other sites More sharing options...
Neon Reefer Posted May 18, 2013 Author Share Posted May 18, 2013 10gReef Thanks for the reply! Good to hear you are happy w/ the flood over your sump. I have power compact in my 28 gal now. Heat is an issue and I have to run a 1/10th chiller to manage it. House gets up to 80+ in the summer. Going to use the same chiller on this tank so it would seem only LED is the answer. I was thinking 14K 100 watts and 455nm Actinic Blue 40 watts would cover the spectrum except for Red which i was going to suppliment w/ 20 - 40 watts. Really just not sure if 12500 Lumens is enough for a 75 gal tank and SPS which would be in the upper half w/ LPS in the lower half. Does anyone know if this seems to be enough. I would gues these lights are 2-3 times brighter than standard wattage like VHO. So can I assume in standard terms these lights are around 420 watts max and probably more like 350 standard watts. Looking for a total 0f 400 watts over this tank. Does that sound about right?. Quote Link to comment Share on other sites More sharing options...

Looking for a total 0f 400 watts over this tank. Does that sound about right?. Why would you assume this and what lead you to thinking it? I run multiple tanks and multiple systems. None have a chiller, all use led lighting/manifold to reduce heat from equip. My tanks don't go above ambient house temps. Quote Link to comment Share on other sites More sharing options...

Well, the Epistar LED emitters and chips are rated at ~ 90 Lumens per watt, as per research. And in general LEDs dependent upon reflectors ect… are usually considered to be 2 – 3 times brighter than conventional and when trying to compare by wattage which is not considered to be the best source, are usually 2 – 3 times higher. Is this not correct? The math shows: (90 Lumens X 140 watts = 12,600 Total Lumens) and @ 2.5 X watts average per conventional (2.5 X 140 =350watts) I have been told that 400 watts of T5 lighting would be a great source for growing SPS. But do not have any idea what the lumen or PAR of this is. So I am trying to compare apples to oranges to get the solution. LOL The only reason I do not just go the T5 route is I am afraid of any heating issues w/ the T5s. LEDs have little heat source and would save me $150 in cost per year in bulbs. And for only $100 more than T5 initial cost I could be in these LEDs. Quote Link to comment Share on other sites More sharing options...
(Bio)³ Posted May 18, 2013 Share Posted May 18, 2013 Led are tested at factory for milliseconds. They tell the highest output in that short blast. As heat builds up and you take in drivers/wires it starts going down. More heat, less output. Try measuring it after its warned up and it won't be as strong.
